Low Collateral Damage Explosive Reactive Armour
Explosive reactive armour (ERA) is commonly used to defeat shaped charges.
SPONSOR: The Defence Academy of the UK
Explosive reactive armour (ERA) usually consists of a tri-plate assembly of high explosive sandwiched between two plates of steel. As a shaped charge jet penetrates the outer steel plate, the high explosive detonates and propels the two steel plates apart. The interaction of the flying plates and the shaped charge jet results in jet disruption and consequently a reduction in jet lethality. ERA is the most effective means of defeating shaped charge jet warheads that is currently fielded. However, steel flyer plates pose a considerable risk to dismounted troops, civilians and other vehicles (such as low flying aircraft). This means that ERA can only be applied on limited sections of the armoured fighting vehicle where the flyer-plates do not pose a significant risk to others. This work examined the various options of reducing collateral damage from ERA flyer plates.
